Bug description:
  [Impact]

  Currenty powerpc image builds are failing on xenial. livecd-rootfs is
  used to build our Ubuntu images and it depends on ubuntu-image.  With
  ubuntu-image 1.7 the snapd dependency was bumped to >= 2.38; which is
  not satisfiable on powerpc because snapd is not buildable on powerpc
  with gccgo (vs golang).

  [Test Case]

  Build test images on powerpc, those should now succeed.

  [Regression Potential]

  None. This is only an arch-specific dependency change which was never
  used (as it was not possible to work).

  [Original Description]

  livecd-rootfs is used to build our Ubuntu images and it depends on ubuntu-image.  With ubuntu-image 1.7 being published to xenial-updates the diff
  shows that the versioned dependency on snapd was bumped to >= 2.38; which is not satisfiable on powerpc because snapd is not buildable on powerpc with gccgo (vs golang).

  This affects xenial cloud image builds.

  added a depends on ubuntu-image but that package is not available on
  xenial for powerpc.  So powerpc image builds are failing. :(
